Changes things 2Claude Code: ask
  • cheapest_weekendsThe cheapest weekends from one origin across every destination that has a calendar under these filters, sorted by price.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    The cheapest weekends from one origin across every destination that has a calendar under these filters, sorted by price. Optional month filter (yyyy-mm). Takes the same filters as weekend_prices. This tool reads what is already priced; it does not search every destination. A destination that is absent can be priced with one weekend_prices call for that pair. Pro only: this tool is Anywhere (every destination from one origin). Without Pro it answers pro_required with the Anywhere page url. One route at a time is free with weekend_prices.
  • weekend_pricesEvery weekend of the next 12 months for one origin-destination pair, with the cheapest round-trip price per weekend and the time the price was observed ("as_of").No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Every weekend of the next 12 months for one origin-destination pair, with the cheapest round-trip price per weekend and the time the price was observed ("as_of"). Cached prices answer at once; weekends not priced yet are searched live during the call, the way a page visit searches them (usually 10-40 s, at most ~55 s). If the search does not finish, the answer says which weekends are still open and to call again. Takes every filter the route page has: trip shape (combo), cabin, stops, passengers, departure and return time windows, currency. Free: fri-sun, economy, any stops, any passenger mix, no time window. Pro session cookie: other combos, other cabins, time windows.
Only reads 1Claude Code: allow
  • list_originsReturns the departure airports (IATA) that have at least one priced weekend calendar, with the count of priced destinations per origin.No findings

    Why it is in this group

    • The name "list_origins" says "list": a word for reading.
    Description, as the server wrote it
    Returns the departure airports (IATA) that have at least one priced weekend calendar, with the count of priced destinations per origin. Start here to learn what cheapest_weekends can answer at once. weekend_prices works for any airport pair and searches live when needed.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
